Coincidentally to this thread, I was reading a story at lunch about the anniversary of Billy Joel's "The Stranger". It had four hits on it:

Scenes from an Italian Restaraunt
Movin' Out
Just the Way You Are
Only the Good Die Young

One of these had a chorus. Another had a repeated refrain which might almost count as one. The other two (including the biggest hit of the four) had no chorus....
